If you've tried a brand of blade in every razor you use, and if it's done poorly in all of them, and if you gave it another shot just in case it was your quality of lather (QoL) that was to blame—then it's reasonable to "never use another".
But it's been my experience that an awful blade in one razor can be wonderful in a different razor.
